90% blockage

I went in to the cath lab on this past Monday. When I came out the MD informed me, I have a blockage in my right coronary artery. The Right artery is full metal jacket. He didn't stent this blockage. He said all the heart muscle to the right is dead so there is no need to stent the spot. Am I going to have a MI when this spot completely closes off?
James Beckerman, MD, FACC responded:
It sounds like your cardiologist believes that you have already had a heart attack in the region of the heart muscle that's supplied by the right coronary artery - so improving the blood flow to that area would not be expected to improve the heart function.

There are some tests that can be used to assess whether or not there is living heart muscle in that area, including a stress echocardiogram, and nuclear viability test, and an MRI. If you are interesting in pursuing things further, it may be reasonable to discuss some form of "viability study" with your doctor.
Saharane replied to James Beckerman, MD, FACC's response:
I did have a heart attack there 5 years ago caused my blood clots from spontaneous dissection in the right coronary, and two branches off there. I keep developing scar tissue to the right where it branches into two arteries. I have already had stress echos, and a PET scan in April and May. He said when nitro doesn't help my angina then I should go to the ER.
